Valve has launched a new initiative that allows developers to introduce their game ideas on the Steam Greenlight service for free.
A new Concepts page, which is separated away from the main games section on Greenlight, allows any idea to receive feedback and votes to gauge how popular it is among the community.
However, it is not part of the main Greenlight process, which costs $100 for a developer to join and allows game ideas to be fully published on Steam if enough positive votes are cast.
The introduction of Concepts comes weeks after Valve was criticised for introducing a pay-wall to the Greenlight service. The company said the cash fee - which ultimately goes to a chosen charity -was necessary to curb the number of fake and spoof game ideas.
Valve said the Concepts section "is intended for items looking to gather feedback from the potential customers and begin building a community".
"If you like projects, feel free to rate them, favourite them, and leave feedback for the developer. The voting here serves only to give the developer data and reactions and doesn't work toward getting the game distributed on Steam."
A selection of the Greenlight Concepts can be found here.
Valve is now accepting non-gaming software on its Greenlight service.
